Members of the European Parliament (MEPs) are elected by the population of the member states of the European Union (EU), divided into constituencies.
Belgium, France, Ireland, Italy, Poland and the United Kingdom are divided into constituencies, while the other member states have a single national constituency. In Germany, political parties are entitled to present lists of candidates either at Länder or national level.
The Kingdom of Denmark was also historically subdivided in two constituencies, with a separate one for Greenland which was dissolved in 1985 after the autonomous country in the Realm withdrew from the EEC (later expanded to become the EU).
Currently, all member states hold elections to the European Parliament (EP) using various forms of proportional representation.
The number of representatives per head of population varies widely across constituencies. For example, Malta has one representative for every 70,000 people, while Podlaskie and Warmian-Masurian (Poland) has only one seat for every 1,326,000 people. The quantity of MEPs representing each country, anyway, is approximately proportional to the population of that member state within the European Union.
